Abstract To control and monitor strength training with a barbell various systems are on the consumer market. They provide the user with information regarding velocity, acceleration and trajectory of the barbell. Some systems additionally calculate the 1-repetition-maximum (1RM) of exercises and use it to suggest individual intensities for future training. Three systems were tested: GymAware, PUSH Band 2.0 and Vmaxpro. The GymAware system bases on linear position transducers, PUSH Band 2.0 and Vmaxpro base on inertial measurement units. The aim of this paper was to determine the accuracy of the three systems with regard to the determination of the average velocity of each repetition of three barbell strength exercises (squat, barbell rowing, deadlift). The velocity data of the three systems were compared to a Vicon system using linear regression analyses and Bland-Altman-diagrams. In the linear regression analyses the smallest coefficient of determination (R2.) in each exercise can be observed for PUSH Band 2.0. In the Bland-Altman diagrams the mean value of the differences in the average velocities is near zero for all systems and all exercises. PUSH Band 2.0 has the largest differences between the Limits of Agreement. For GymAware and Vmaxpro these differences are comparable.

Store atmosphere is a condition in a store that is formed by the tangible and intangible components, which can influence consumer behavior, such as customer satisfaction. Customer satisfaction is the level of one's feelings after comparing the performance or perceived value with expectations. This study used a quantitative method, such questionnaires which distributed to 142 respondents and also the observations results. In addition, this study uses three types of analysis to achieving the objectives, namely descriptive analysis, correlation analysis and linear regression analysis. Meanwhile, the results of this study indicate that store atmosphere good categories with a mean value of 3.72 and customer satisfaction at high category with a mean value of 4.09. In addition, the coefficient of determination test indicates that the effect of store atmosphere contributes 27.7%to customer satisfaction and the other of 72.3% is the contribution of the influence from the other variables which not examined in this study. Based on test results obtained linear regression equation such Y = 26.711 + 0,367X. This is show that if there is additional to the store atmosphere, the customer satisfaction will be increased by 0,367. And the results of hypothesis testing indicate that there are significant influences between store atmosphere and customer satisfaction at theToko Buku Togamas Branch Supratman Bandung.

Abstract The shear strength of the soil is an important factor to know the internal resistance of soil against external loads causing shearing forces. Shear strength parameters are mandatory for the analysis of load bearing capacity of the soil, the stability of Geotechnical structures and in analysing stress and strain characteristics of soils. The undrained shear strength is one type of shear strength parameter. This parameter is conducted by undisturbed samples. But due to handling, transportation, release of overburden pressure and poor laboratory conditions, it is difficult to obtain accurate undisturbed samples. So, prediction of undrained shear strength parameters (cu) for cohesive soil with the help of compaction characteristics provides a good alternative to minimize this problem. Therefore, this study was conducted to develop the correlation between undrained shear strength values with soil compaction characteristics specifically located in Burayu town. The study was carried out using thirty samples collected from the town. By using the test result regression based statistical analysis was carried out to develop the intended correlation. The parameters considered for this study are Atterberg's limits, Grain size analysis, Specific gravity, Compaction tests and unconfined compression test. The test procedures were based on AASHTO and ASTM laboratory test standards. These parameters are used to establish equations of correlations between undrained shear strength values with soil compaction. The soil type found in Burayu town was highly plastic red clay soil. Based on both single and multiple linear regression analysis relatively good correlation is obtained by combining undrained shear strength (qu ) with maximum dry density and optimum moisture content of red clay soil. From the correlation analysis the equations developed are qu = - 3105 + 1625 MDD + 40.9 OMC with coefficient of determination of R2 =0.828 for multiple linear regression and qu= - 1473 + 57.8 OMC and qu= - 4861 + 3910 MDD with coefficient of determination of R2=0.787 and R2 =0.601 for single linear regression respectively. Generally, the intended correlation obtained from the study area fulfil the basic requirement of regression.

This research was conducted at PT Dwigunatama Bekasi, Indonesia, with the title "Theinfluence of the work environment on employee performance at PT Dwigunatama Bekasi,Indonesia". The purpose of this study was to determine the effect of the work environment onemployee performance at PT Gunatama Bekasi, and how big its influence. The research methodused is the field reserch and librarary reserch method with a correlational approach where inthe process of collecting data a direct observation is conducted on the company in the form ofobservation and questionnaire distribution. work environment is anything that is aroundemployees and that can affect employees. Employee Performance is the spirit of work that is thedesire and sincerity of someone doing a good job and being disciplined to achieve maximumwork performance. The linear regression test is y = 2.55 + 0.93 X and the correlation test is 0.90which means that the effect is quite strong. Test the coefficient of determination of 81% and theremaining 79.03% is influenced by other factors. The hypothesis test is t arithmetic 14.51 and ttable 2.010 means t arithmetic> from t table then Ho is rejected and Ha is accepted which meansthere is a strong enough influence between the work environment on Employee Performance.
